From this sections on we describe the TS itself, starting with
general design philosophies.
The design process should follow a general design philosophy.
The design rules below should help in finding solutions, in particular
if decisions cannot by uniquely derived from other design objectives.
high reliability
highly modular architecture with a high number of exchangeable
standardized off-shelf components, where each component has a known,
simple and reliable functionality
well defined, standardized and open interfaces
easy to maintain, assemble/disassemble, if possible
automatically
the transport network should be extendable qualitatively (with
more sophisticated technologies) and quantitatively (network
expansion to an arbitrary size)
